Sesame, salt, and substance. A flagship bake.
Summary
A new study reveals that unaccounted-for emissions of ozone-depleting substances used as chemical feedstocks have increased since the 1987 Montreal Protocol, potentially delaying the recovery of Earth's ozone layer by about 7 years. While the Montreal Protocol is widely considered a success, the growing use of these exempted chemicals in manufacturing processes poses a significant and overlooked threat to ozone layer restoration.
Key quotes
· 3 pulledThe Montreal Protocol is such a success story that these ozone-harming sources are becoming relevant. A few decades ago, they were drowned out.
New research found that the use of ozone-depleting substances used as feedstocks—chemicals used in the making of other chemicals—has not waned over time. In fact, their use has increased since the treaty's adoption in 1987.
A hole in the Montreal Protocol could delay the recovery of Earth's ozone layer by about 7 years.
